Not to mention the fallout from emphasizing that the perpetrator is a Sikh given the amount of harassment and attacks Sikhs have had to endure post-9/11 by ignorant assholes who think they're Muslims (not that it would be right to harass or attack Muslims either). People would be (rightfully) upset about it, and the outrage would far exceed any of this nonsense about whitewashing a character that was already played by a white man of European descent once before. It's a no-win situation.

Did I mention I hate PC ? We basically have to stick to white villains, now.
